FIELD: engine building.
SUBSTANCE: invention relates to rotary-vane internal combustion engines. Essence of invention consists in that engine comprises chamber, in base of which three arcs of equidistant circles connected to each other by curve, built of points, which have equal distance to inner surfaces of arcs along straight lines passing through central point, from which equidistant circles are located. Said point is the center of the figure base with invariable distance between two points located in one plane, lying on the surface of the chamber and connected by a straight line passing through the central point. According to the invention, the engine is made of sections with shafts, in which blades are made with possibility to provide passage of shafts located one in the other and rotating in different directions. Engine with two independent rotation shafts having common rotation axis enlarges the range of possible application of this type of engine.
EFFECT: technical result is reduction of energy losses due to reduction of number of friction pairs, reduction of number of assembly units and transfer of energy via blades directly to rotor.
